Telkoms mess, I have to clean

I opened a new Telkom contract not long ago for a new cellphone , what happened was I gave my new banking statements with my new account details which is a FNB account ,but the telkom agents had opened a new contract with my old Nedbank account that was used when I opened my first telkom contract along time ago ,that is now a closed account as I do not work for Nedbank anymore, and I now have a FNB account which I use, what I have a problem with is I ordered to have a debit order on my FNB account when opening the account I called telkom and told them about this problem , cos the first month the debit was suppose to go off it didn’t it was trying to take the balance from my Nedbank account , which is closed, I then called telkom to tell them that they need to amend the banking details which the lady said she done so to my new account , now it seems as if nothing has gone off for this month again and you ****ing people have brought my credit score down for you own **** up of putting the wrong banking details on my account, remove the bad **** you added to my credit record because now I’m in the process of moving house all my stuff is paid but my credit is bad and I can’t get a ****ing place to stay for my wife and 5 month old because telkom has ****ed my credit because of their own ****ing wrong doing by putting debit orders on old closed accounts and then I have to call and fix it because telkom couldn’t care less about calling to resolves **** you always have to do the work for telkom till you come and have to have hellopeter complaints to get anything done properly , I’m so tired of you people catching on the biggest **** in your organization.
